# IP INTELLIGENCE BRIEFING: 54.39.0.212/32

Classification: MODERATE RISK β€” Cloud Infrastructure with Elevated Neighborhood Threat Profile

Generated: IPDebrief Intelligence Analysis

Date: Current Analysis Cycle

---

## EXECUTIVE SUMMARY

IP 54.39.0.212 is a cloud infrastructure endpoint hosted on OVH (ASN 16276) within the 54.39.0.0/24 subnet. While the individual IP presents a moderate risk profile (risk score: 40), the subnet demonstrates elevated threat activity with a 71.88% abuse density classification. No direct threat indicators were observed, but contextual neighborhood risk warrants defensive consideration.

## OWNERSHIP & GEOLOCATION

AttributeValue
**ASN**16276 (OVH)
**Organization**Dmytro, Ahrefs Pte Ltd
**Network Block**54.39.0.0/24
**RIR**ARIN
**Geolocation**Canada, Quebec, Beaucharnois
**Infrastructure Type**Cloud Compute
**Hosting Status**Active

Geolocation Validation: INCONSISTENT. RTT measurements indicate 30ms latency with a 5,629km distance claim, creating a 112.6ms minimum RTT violation. This suggests potential geolocation spoofing or data inconsistency requiring validation.

---

## THREAT PROFILE

IndicatorStatus
**Known Attacker**No
**Tor Exit Node**No
**Spam Source**No
**Blacklist Count**0
**DNSBL Listed**1 of 8 lists
**Campaign Likelihood**None

Threat Signals: No active threat indicators detected. No known malware campaigns, attacker signatures, or spam associations observed.

## NEIGHBORHOOD ANALYSIS

The 54.39.0.0/24 subnet shows significant threat concentration:

MetricValue
**Abuse Density**71.88%
**Subnet Classification**High Abuse
**Total Siblings**256
**Active Siblings**227
**Threat Siblings**184
**Inherited Risk Score**28

Risk Context: This subnet's elevated abuse density (71.88%) indicates that threat activity is concentrated within the broader network segment. While the target IP lacks direct indicators, the neighborhood context suggests potential for coordinated or shared infrastructure misuse.

---

## DNS & SERVICES

AttributeValue
**PTR Hostname**proxy-ca004-san212.ahrefs.net
**Forward Confirmed**No
**Hosted Domain**ahrefs.net
**Open Ports**None detected
**Service Status**Firewall / No Services

DNS Validation: Reverse DNS records exist but forward resolution is unconfirmed, indicating the IP may be in a non-public-facing or internal network segment.

## RECOMMENDED ACTIONS

Based on the moderate risk score and high-abuse neighborhood context:

Firewall Recommendations:

```bash

# iptables

iptables -A INPUT -s 54.39.0.212 -j DROP

# nftables

nft add rule inet filter input ip saddr 54.39.0.212 drop

# nginx

deny 54.39.0.212;

```

WAF/CDN Integration:

Implementation Note: Consider implementing subnet-level monitoring or blocking (54.39.0.0/24) given the 71.88% abuse density, though this should be weighed against potential false positives from legitimate cloud infrastructure.

---

## ANALYST NOTES

1. Context-Aware Risk: While the IP shows moderate risk individually, the subnet's high abuse density suggests broader infrastructure concerns.

2. Geolocation Inconsistencies: RTT violations warrant periodic revalidation of geolocation data.

3. Cloud Infrastructure: No direct services or open ports detectedβ€”typical of cloud compute environments.

4. Monitoring Recommendation: Track subnet-level activity patterns to identify coordinated threats.
